I thought I was having software issues on my MVR because while I was fine tuning my Evics RVW, I plugged it into my MacBook and when i went to the switch option to make changes on the RVW the menu would not open up it would just show a blank page. I reinstalled software and it still did it. And I even thought something might be wrong with the EVIC itself so I turned off and on the EVIC and still the same. But the solution here is when u plug in your EVIC, make sure your EVIC is in VV mode and once i did that and plugged in the EVIC I was able to get into the switch menu. Just wanted to share if you ever have that problem
